As a pragmatic and safety focused diver I always look for good solid products - this tank falls into this category, not too much to say - nothing fancy, it does what it is supposed to do...the only slight oddity (to me) - yes, its black!

This is a great tank for the money. I just got the Sherwood tank in bright yellow and as with all of their products it was outstanding. There was one hiccup in that the valve was not included in the box with the tank, but with one phone call the scuba.com folks made it right and got the valve to me. No problems getting the tank filled with the visual inspection sticker on the tank.

Tank and K-valve work great. I like the fact that its visualy inspected as this eliminates problems getting it filled at my local dive shop.

Im new to diving is this a good tank to have??

Hello Hayden, Thank you for your inquiry!

When purchasing your cylinder, be sure to include a tank boot, a valve protector and a tank carrier. http://www.scuba.com/scuba-gear-200/043077-042005/Sherwood-80-Cubic-Foot-Aluminum-Tank.html If you have any questions or wish to place an order, please call us at 1-800-247-2822 or 949-221-9300.

trace:

how many minutes of air dose the tank hold

Clarke(Certified Scuba Instructor at Scuba.com):

Hello Trace, Thank you for your inquiry! Excellent question… “How many minutes of air does this tank hold”, is a question that cannot readily be answered due to too many variables; Your depth, the dive activity, the diver’s conditioning, ect. You can calculate your SCR (Surface Consumption Rate), with the NAUI Scuba Dive Calculator Surface Air Consumption Wheel: http://www.scuba.com/scuba-gear-120/058048/NAUI-Scuba-Dive-Calculator-Surface-Air-Consumption.html If you have other questions, need help or would like to place an order, please contact SCUBA.com by calling 800-247-2822 <> 949-221-9300 or e-mail us at: info@scuba.com

Daniel:

I have a Sherwood 80 tank which I think its from the year 97, is it safe for me to use?

Darrick(Certified Scuba Instructor at Scuba.com):

Hello Daniel, as long as it is current in both the VIP (which is a sticker) and Hydro date (which is stamped into the neck of the tank) it is ok to get filled. If either of these date are expired that you will need to get your tank serviced. If you have any worries then I would suggest taking it to your local scuba shop and have them take a look at your tank. If you have any other questions please feel free to give us a call at 1.800.347.2822

Rick:

I have heard that aluminum is not healthy for us. Have you heard any pros/cons along this line with aluminum vs steel?

Bob(Certified Scuba Instructor at Scuba.com):

Aluminum is the most common material used for the manufacturing of scuba cylinders. Of all the pro/con arguments between aluminum and steel scuba tanks, this isn't one to concern yourself with.

ben:

It the 25.9" length with or without the included K-valve. Also, Im using this in a pneumatic scenario and was wondering if anyone knew a lighter tank that is still as stable?

claus:

I am looking for an aluminium tank whose diving depth capacity is 40m.

Bob(Certified Scuba Instructor at Scuba.com):

Cylinders are not typically rated in diving depth capacity. Technically speaking, a 6 cubic foot tank will get you to 100 ft. It's not enough air to get back or do anything once you get there, but it's enough air to get there. The average scuba tanks used for divers at all the recreational depths is the Aluminum 80 cubic foot tank.

Christian:

Is the 25.9" length with or without the included Pro Valve-Standard?
Thank You!

Darrick(Certified Scuba Instructor at Scuba.com):

Hello Christian, yes that is the total height of the tank with the valve. If you like you can contact the manufacture directly at (800) 347-9766.

Michael:

How well does the finish hold up on the tanks? What exactly is the shot blast finish?

Bill(Certified Scuba Instructor at Scuba.com):

The tank finish will hold up at the same rate of care you give it. With any painted surface dings and chips will happen as a tank roll and bang around. A shot blasted tank is a bare aluminum tank that is blasted with beads to give it a matt look.

Joe:

Hello, I am brand new to diving and I am wondering where you stand on the steel vs aluminum tank debate? I have heard that aluminum is bad because you will surface to fast but that it holds up better. I have heard that steel is the way to go because it keeps you down but it doesnt last nearly as long. What do you think? Thanks for the help!

Arthur(Certified Scuba Instructor at Scuba.com):

Good morning, the AL 80 is the most common tank used world wide mainly because its cheap. True they are slightly neutrally buoyant when the tank gets low and does cause new divers to have difficulty staying neutral at their safety stop. High pressure steel tanks don't do this. They can both hold the same amount of air and if cared for (visual inspection every year, and hydro tested every 5 years) will last just as long.

Dick:

Is the valve to connect my regulator included in the price.

Darrick(Certified Scuba Instructor at Scuba.com):

Hello Dick, yes the valve that connects to the tank is included in the price of the tank.

Brandon:

How does the xs scuba compare to the Sherwood cylinders? They are both made by Catalina. Do you have any cylinders made by worthington.

Darrick(Certified Scuba Instructor at Scuba.com):

Hello Brandon, the XS Scuba tanks are made by Worthington not Catalina. Both tanks perform the same just different manufacture.

Hugh:

How many high pressure and low pressure ports does this tank have. I want to run a primary console computer as well as a backup wrist computer with a pressure transmitter so I will need an extra high pressure port to connect the transmitter to. Thanks

Bob(Certified Scuba Instructor at Scuba.com):

It has none of either. The HP and LP ports are found on the 1st Stage of the regulator.

Scott:

Does the sea turtle come with the tank? Or do I have to buy it separately? Sorry, Im new to underwater basket weaving.
Thanks!
-Scott

Arthur(Certified Scuba Instructor at Scuba.com):

Hello, tanks are always sold individually unless you are getting a twin tank setup.

Hugh:

Can this Sherwood 80 cubic foot aluminum tank be used with enriched air/nitrox?

Arthur(Certified Scuba Instructor at Scuba.com):

Hello, yes they are compatible to 40%.

More About This Product

TANKS & VALVES: Sherwood Valve

PRODUCT FEATURESThe most used valve in diving. The critical link between your regulator and tank, our patented Sherwood valve was designed specifically to handle today’s high-performance regulators.

Aluminum TanksAluminum tanks are cost efficient, long lasting, and readily available, which is why they are easily the most common scuba diving tanks in the world. Lighter than steel tanks, aluminum dive tanks are easier to transport and swim with, giving your shoulders and arms a break on long treks.

Because of their light weight, some aluminum tanks will begin to float at the end of a dive, once the oxygen supply is nearly depleted. To combat this, it's common to counter-weight an aluminum dive tank with approximately 4 pounds. However, 'Compact Neutral' aluminum tanks are made with thicker walls, which increase the weight and help to counteract the positive buoyancy problems at the end of a long dive.
